C++和excel交互

最近碰到在c++端打算把数据写入交互excel，一开始觉得opencv也有对应的库函数，后来发现c++端使用IO流就可以实现，现在记录一下：

// openblas-test.cpp : 定义控制台应用程序的入口点。

#include "stdafx.h"

using namespace cv;
using namespace cv::cuda;

void nonlocalMeansFilter(Mat&, Mat&, int, int, double, double);
void writeToExcel(Mat, string);
*/
using namespace std;

void write_to_excel(string filename, bool&flag);

#define INVALID -1

int main(int argv, char**argc) {
	/*
	Mat srcImg = imread("D:\\project\\Image\\lena.jpg", 1);
	Mat dst1, dst2, dst3;

	// bilateralFilter(srcImg, dst1, 15, 130, 200);

	// writeToExcel(srcImg, "2.xls");


	imshow("src", srcImg);
	// imshow("bilateralFilter result", dst1);

	// fastNlMeansDenoising(srcImg, dst3);
	// nonlocalMeansFilter(srcImg, dst2, 3, 7, 25, 25);
	*/

	bool flag = false;
	write_to_excel("test2.xls", flag);

	// imshow("fastNlMeansDenoising result", dst2);

	// waitKey(0);

	return 0;
}

	{
